DEVICE EUR TREATING. CHOCOLATE MASSES CR OTHER MATERIALS,

Application filed August 8. 1921, Serial No. 490,767.

To all whom t may concern.'

De it known that l, FnniDmoI-r FRANZ WILHELM SCI-IILDENER, residing at Zschieren, near Dresden, in the Republic of Saxony, Germany, have invented certain new and useful Improvements in Devices tor Treating Chocolate Masses or Other Materials (for which l have :tiled applications in Germany, under Sch. 56,983 X/ 1, dated 13th of December, 1919; Great Britain, under Nr. 10,87% dated 14th of April,1921; Switzerland, under Nr. 11,970, dated 29th of March, 1921), of which the 'following is a specification.

This invention relates to a device for treating chocolate masses or other materials by means of mixing and lrneading elements moving about in a heated container provided with a. discharging outlet.

The invention consists more particularly in the combination of the mixing and kneading elements with other elements circulating around the :former and turning the material over, this combination being ef- 25 ected in such a manner that the mass moving to and fro is pushed with every movenient into the circulating mass, and that inversely the circulating mass is pushed into the mass moving to and fro. This is always effected at other continuously chang'- ing points of the container and parts of the mass, the latter being continuously propelled and turned over by the circulating members, e. the reversing` blades. Such mixers and Scrapers are used, e. g. in crush- :ingmills and rotary grinding mills, as is well known to those skilled in the art, and in these the mixing elements move on cycloida lines or rotate in the manner of a. gyroscope. Up till now, however, these movements were not performed in combination with a mixing and hneading body describing a reciprocating movement in the container.

n the drawing atlixed to this specification and forming part thereof- Fig. 1 is a plan view of an agit-ating device constructed according to the present invention.

Fig. 2 is a vertical section taken substantially centrally through the same.

The untreated, raw chocolate mass is placed in a heated circular container T, in which it is continuously moved to and fro,

similar to the mass in a longitudinal grinding mill, by means of a rolling cylinder or similar member WV. In order to subject all and any parts of the mass to the treatment, a number of mixing and scraping blades A, B, C and D rotate around the inner wall of the container T and about the roller W. The. blades A, B, C and D are connected to a toothed ring Z mounted to slide on the upper edge oitI the container. The ring Z may be turned by a main driving gear E, and the blades A, B, C and D are secured to arms F which extend down into the container and carry the blades in the direction oic the arrow, Fig. 1. The mixing blades B, C and D recede inwardly from the wall of the container and push the mass, not touched by the roller, towards the same by dellecting the mass toward the center of the container', the roller continuously forcing the mass before it into the path of the mixing blades, so that the process is continuously repeated. The blade A is in the form of a scraper travelling at the same time along the inner wall of the container and scrapes the mass from the inner wall, thereby preventing the mass from being burnt and insuring that it be mixed again with the body of the mass.

By thus advantageously combining the action ot the reciprocating and rotating elements, or means for agitating the chocolate mass, the latter is continuously kept in motion. spread out and compressed again, pushed one part into the other, turned over and thoroughly mixed and lnieaded. The mass lying at the bottom near the inner face of the side wall oi the container is lifted up and turned over by the mixing blade B in its clockwise movement in a similar manner as the ground is broken and laid over by the share of a. plough, whilst the blade C acts in a reverse manner, pressing the mass downward again, this blade being high at its forward and low at its rear end. The blade D abuts with its edge against the side wall of the container and, with its rear concave end, juts out towards the center of the container in a slanting position, so that the blade in its clockwise movement pushes the mass from the circumference towards the center of the container, where the mass is subjected again to the action of the roller, and thus the cycle. automatically discharged through the outlet O in the bottom of the container.

I claim l. In a device for treating chocolate masses and the like, a container adapted to receive the mass, a reciprocating member mounted Vttor travel in a rectilinear direction for agitating the mass, and'means arranged Within the container' and movable relatively thereto for travel in a circular path to direct the mass centrally from the Wall or' the container-'into the path of the reciprocating member.

2. In a device for treating chocolate masses or other materials, a stationary container adapted to receive the mass,A a reciprocating 'member mounted to travel ina right line path through the mass in the container to; agitate the mass, and laterally disposed means in the container for movement in the mass, to direct the same into the path of said reciprocating member.

' 3. In a device for treating chocolate masses and other materia-ls, a container adapted to receive the mass, a roller mounted for reciprocating in ak right line path in the container for agitating the mass, and means mounted to travel in a path extending along the inner Wall of the container for operation about said reciprocating mem- The finished chocolate mass may be `tainer for operation about the roller to defleet the mass displaced by the movement of Y the roller back into the path of the roller.

5. In a device for treating chocolate and other masses, a container adapted to receive the mass, a roller mounted to reciprocate Yin a right line and diametrically ot' andV in the container iforagitating the mass, and a plu rality of circularly travelling agitators mounted in the container :tor operation over the inner Wall of the container and about the roller for delecting the mass inwardly into Vthe path of the roller in various directional streams and for removing accumulatio-ns of the mass romthe inner Wall of the container to Vprevent sticking of the same and insure the thorough admixing of the mass.

In testimony whereof I aiiix my signature in presence of two Witnesses.
